Abstract
The utility model relates to a connecting mechanism with guiding function of a connecting rod and a sphere screw rod. The connecting mechanism consists of the connecting rod, a ball-head screw rod, a locating flange and a bolt. The locating flange can compulsively ensure that the axle center of the ball-head screw rod is concentric with the axle center of the locating flange, thereby avoiding the defect that the part between screw threads is deformed or even damaged and avoiding the accident that the screw threads between the connecting rod and the ball-head screw rod are not easy to be adjusted or the equipment is damaged as the screw threads are partially stressed over heavily due to the unbalanced loading of the stress between the connecting rod and the ball-head screw rod.
Description
Technical field
The utility model relates to the bindiny mechanism of the connecting rod and the ball screw rod of the bindiny mechanism of a kind of connecting rod and spheroid screw mandrel, particularly a kind of guide function.Belong to the metal forming machinery technical field.
Background technology
Connecting rod and ball screw are the critical function parts of forcing press, and they transmit pressure by the cooperation of both internal and external threads, simultaneously by the adjusting of the realization of the controllability between both screw threads to forcing press operating mechanism.At present, the screw thread that usually takes place in the use of reality between the two is difficult to regulate, even the phenomenon and the problem of thread damage appear, cause the main cause that this phenomenon takes place to be: connecting rod and the bindiny mechanism of ball screw directly are connected by both screw thread, this method of attachment is not too reasonable, because connecting rod and the ball screw transmission of pressure at work always do not carry out along both axis, so cause the stressed generation unbalance loading between the screw thread, local pressure is excessive, thereby causes deforming between screw thread even damaging.
Summary of the invention
The purpose of this utility model is: the bindiny mechanism that a kind of connecting rod and ball screw rod of guide function are provided, overcome existing press connecting rod and ball screw owing to adopting direct thread connecting mode to exist: since connecting rod and ball screw at work the transmission of pressure always do not carry out along both axis, cause the stressed generation unbalance loading between the screw thread easily, local pressure is excessive, causes the defective that deforms between screw thread even damage.And connecting rod that causes therefrom and the difficult adjusting of the screw thread between the ball screw, or the accident of device damage.
Solving the technical scheme that its technical problem adopts is: at the lower end of connecting rod oral area, one location flange is set, the intermediate fabrication light hole of locating flange, the unthreaded hole axis that guarantees flange simultaneously when locating flange is installed is concentric with the silk axially bored line on the connecting rod, simultaneously in above-mentioned guide flange, the diameter of its center unthreaded hole is a bit larger tham the big footpath d2 of the internal thread on the connecting rod or the externally threaded big warp above the ball screw to d2, in the part of ball screw near bulb, make one section light cylinder, the external diameter free size of its light cylinder is identical with the free size of the center unthreaded hole of locating flange, and both form small matched in clearance on tolerance.
The utility model is to realize like this, the lower end oral area that locating flange is fixed and is installed in connecting rod with bolt, the axle center of guaranteeing its unthreaded hole b when mounted is concentric with the axle center of connecting rod, is installed to the bulb leading screw in the screwed hole of connecting rod from the mider hole of locating flange; The unthreaded hole axis that guarantees flange simultaneously when locating flange is installed is concentric with the silk axially bored line on the connecting rod, simultaneously in above-mentioned guide flange, the diameter of its center unthreaded hole is a bit larger tham the big footpath d2 of the internal thread on the connecting rod or the externally threaded big warp above the ball screw to d2, in the part of ball screw near bulb, make one section light cylinder, the external diameter free size of its light cylinder is identical with the free size of the center unthreaded hole of locating flange, and both form small matched in clearance on tolerance.
The beneficial effects of the utility model are: because locating flange can guarantee forcibly that the axle center of ball screw is concentric with the axle center of himself, so avoided between connecting rod and the ball screw because the stressed screw thread local pressure that unbalance loading caused is excessive causes: the defective that deforms between screw thread even damage, and connecting rod that causes thus and the difficult adjusting of the screw thread between the ball screw, or the accident of device damage.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a schematic diagram of the present utility model.
Shown in the figure: 1, connecting rod; 2, ball screw; 3, locating flange; 4, bolt.
The specific embodiment
Locating flange (3) is fixed with bolt (4) is installed in the lower end oral area of connecting rod (1), the axle center of guaranteeing its unthreaded hole b when mounted is concentric with the axle center of connecting rod (1), is installed to bulb leading screw (3) in the screwed hole of connecting rod (1) from the mider hole of locating flange (3); The unthreaded hole axis that guarantees flange simultaneously when locating flange (3) is installed is concentric with the silk axially bored line on the connecting rod (1), simultaneously in above-mentioned guide flange, the diameter of its center unthreaded hole is a bit larger tham the big footpath d2 or the externally threaded big warp above the ball screw (2) of the internal thread on the connecting rod (1) to d2, in the part of ball screw (2) near bulb, make one section light cylinder, the external diameter free size of its light cylinder is identical with the free size of the center unthreaded hole of locating flange, and both form small matched in clearance on tolerance.
Claims (2)
1. the bindiny mechanism of the connecting rod of a guide function and ball screw rod, it is by connecting rod (1), ball screw (2), locating flange (3) and bolt (4) constitute, it is characterized in that, locating flange (3) is fixed with bolt (4) and is installed in the lower end oral area of connecting rod (1), the axle center of unthreaded hole b is concentric with the axle center of connecting rod (1), in the screwed hole of the connecting rod (1) that bulb leading screw (2) is installed to from the mider hole of locating flange (3), the diameter of center unthreaded hole is a bit larger tham the big footpath d2 or the externally threaded big warp above the ball screw (2) of the internal thread on the connecting rod (1) to d2.
2. the bindiny mechanism of the connecting rod of a kind of guide function according to claim 1 and ball screw rod, it is characterized in that: the axle center of ball screw (2) is concentric with locating flange (3) axle center.
